Hi all,
I have two MPPTs 450/200's they each have 4 trackers totaling 8 trackers.
Questions:
1. Based on the documentation below you should be able to access the *PV* values for the MPPT through solarcharger/PV/x+1. However which ever value(s) I look at it seems to be reporting (this is where I need clarification) either:
1. Combined values for both e.g. if I use solarcharger/Pv/0/P - Don't think its combined e.g. Production is 15KW of PV and on all 4 trackers I can see its producing 50% of that meaning the other 4 should be doing the other 50% of the 15KW
OR
2. It is not listing the second MPPT in the values example of what I can see:
solarcharger/Pv list the following for me:
If I check the influxdb structure it is also confirming that its only seeing one of the MPPT's and 4 of the 8 trackers:
I understand its storing it as an array so 0 = 1 tracker and so on. However it does not show me MPPT2 that has another 4 trackers on it. Am I missing something as below documentation seems to indicate I should be seeing all trackers.
Also if I use solarcharger/NrOfTrackers it is only reporting 4 not 8 (as my system is configured)
2. Is there a way to get the MPPT names from the InfluxDB? So I can relate the trackers to the names?
This is the documentation I am following:
dbus · victronenergy/venus Wiki · GitHub specifically at
Number of trackers: /NrOfTrackers: Number of trackers, usually 1 for all common MPPTs, and 2 or 4 for MPPT RS. PV Array voltages and currents: /Pv/V <- PV array voltage, path exists only for single tracker product (all common MPPTs) /Pv/0/V <- PV array voltage from 1st tracker /Pv/x/V <- PV array voltage from tracker x+1; today's max number of trackers in a single Victron product is 4. /Pv/0/P <- PV array power (Watts) from 1st tracker /Pv/x/P <- PV array power from tracker no. x+1. /Yield/Power <- Total PV power (Watts). Two examples: 1) a solar charger with one tracker has 2 paths: /Pv/V /Yield/Power 2) a solar charger with two trackers has 5 paths: /Pv/0/V /Pv/0/P /Pv/1/V /Pv/1/P /Yield Power
